Cholesterol and You

By: Danielle Kleindl


Cholesterol- a steroid that is in all human and animals. It regulates membrane fluid and acts as a precursor molecule in metabolic pathways. A total level of lessthen 200 mg/dL is desirable, but a level of 240 and above put you at a very high risk for heart disease.


LDL (low density lipoprotein) is the "bad" cholesterol. It is a fatty like substance that collects on the sides of blood vessels making your chances for a heart attack greater.

HDL (High density lipoprotein) is the "good" cholesterol. It is denser then most cholesterol moleculese and it cleans the sides of your blood vessels, then it reuses the LDL to make more HDL.

Healthy HDL

Since HDL is good for you, you need very high levels. Higher than 60 mg/dL is a healthy level, but lower than 40 is unhealthy. If your HDL is too low, there are several things to raise them. Such as..

  • Excersice
  • Stop your tobacco usage
  • Remain a health, consistant weight

Healthy LDL

As said earlier, the higher your LDL levels, the more at risk you are for heart problems. A level of 100 mg/dL of LDL is healthy, and a level of 190 mg/dL is critical to your health. To lower your levels you should the following...

  • Eat a better diet
  • Possibly take medicine depending on the severity of the levels.

Monitoring Your Levels

When you go to a doctor checkup, they usually do blood work. Whenever they test your blood, they check your levels of many things including HDL and LDL. The reason for this is so they can evaluate your total health and see if your at risk for cardiovascular heart disease.

Some other things that are monitored include...

  • VDL (very low density lipoprotein)- distributes your triglycerides to your liver
  • Triglycerides- Helps the body store and give out energy to the muscles.

Saturated, Unsaturated,and Trans Fats

Trans Fats are very bad for you and it raises your LDL levels

Saturated fats also raises your LDL levels

Unsaturated fats is more healthy for you then the above because it protects you from heart disease and lowers triglyceride levels.


A lot of people take your cholesterol for granted until it too late. so take it seriously, eat more unsaturated fats, work out, and live your life healthy!
